Description
Technical Field
The utility model relates to the technical field of optical fiber expanded beam connectors, in particular to a beam expanding structure with a long plugging life.
Background
The optical fiber connector is a device for carrying out detachable (movable) connection between optical fibers, precisely connects two end faces of the optical fibers, so that the light energy output by an emitting optical fiber can be coupled into a receiving optical fiber to the greatest extent, and the influence on a system caused by the intervention of the light energy into an optical link is minimized, which is a basic requirement of the optical fiber connector, and the optical fiber connector influences the reliability and various performances of an optical transmission system to a certain extent. However, in some situations where repeated plugging is required, damage to the lens may occur, and we propose a beam expanding structure with a long plugging life.
Disclosure of Invention
In view of the above problems, the present utility model provides a beam expanding structure with a long plugging life, which has the advantage of not damaging the lens.
The technical scheme of the utility model is as follows:
the utility model provides a high plug life expands beam structure, includes the lens sleeve, the lock pin sleeve has been cup jointed to the outer surface of lens sleeve, lens is installed to the inside one end of lens sleeve, the bi-polar lock pin is installed to the inside other end of lens sleeve.
In a further aspect, the outer diameter of the lens is the same as the outer diameter of the double-ended ferrule, and the lens and the double-ended ferrule are in a concentric coaxial state when mounted inside the lens sleeve.
In a further technical scheme, the core insert sleeve is of a hollow structure, and the lens sleeve can be inserted into the core insert sleeve.
The beneficial effects of the utility model are as follows:
the utility model provides a high plug life expands beam structure, has realized the separation of lens and fiber cable through increasing a bi-polar lock pin, and optical fiber connector still uses conventional pottery lock pin, and in the plug in-process, only pottery lock pin on the optical fiber connector dock with bi-polar lock pin, has guaranteed that the lens is not damaged, has improved life.
Drawings
Fig. 1 is a schematic overall structure of an embodiment of the present utility model.
Reference numerals illustrate:
1. a lens; 2. a lens sleeve; 3. a ferrule sleeve; 4. a double ended ferrule.
Detailed Description
Embodiments of the present utility model are further described below with reference to the accompanying drawings.
Examples:
as shown in fig. 1, a beam expanding structure with a long plugging life comprises a lens sleeve 2, a core inserting sleeve 3 is sleeved on the outer surface of the lens sleeve 2, a lens 1 is installed at one end of the inside of the lens sleeve 2, a double-end core inserting 4 is installed at the other end of the inside of the lens sleeve 2, the outer diameter of the lens 1 is identical to the outer diameter of the double-end core inserting 4, the lens 1 and the double-end core inserting 4 are in concentric and coaxial states when installed in the inside of the lens sleeve 2, the core inserting sleeve 3 is of a hollow structure, and the lens sleeve 2 can be inserted into the inside of the core inserting sleeve 3.
The working principle of the technical scheme is as follows:
wherein the lens 1 and the double-ended ferrule 4 have the same outer diameter and are adapted to the inner diameter of the lens sleeve 2, such that a concentric, coaxial between the lens 1 and the double-ended ferrule 4 is ensured, after which these three parts are inserted as a whole into the ferrule sleeve 3.
During the opposite-end insertion, the insertion core for the opposite-end insertion is inserted from the opening at the other side of the insertion core sleeve 3 and is contacted with the double-end insertion core 4, so that the concentric coaxiality between the opposite-end insertion core and the lens sleeve 2 can be ensured through the insertion core sleeve 3 as long as the outer diameter of the insertion core for the opposite-end insertion is the same as the outer diameter of the lens sleeve 2, the concentric coaxiality between the opposite-end insertion core and the double-end insertion core 4 and the lens 1 can be indirectly ensured, and the communication is ensured.
The foregoing examples merely illustrate specific embodiments of the utility model, which are described in greater detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
